ROBERT BARRIE, OF PHILADELPHIA, PENNSYLVANIA.

BICYCLE-TIRE.

SPECIFICATION forming part of Letters Patent No. 647,213, dated April I,1900,'. Application filed October 29, 1897. Serial No. 656,821. (Nomodel.)

To ctZZ wtom it may concern.-

Beit known that I, ROBERT BARBIE, a citi- Zen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented a new and useful Improvement inBicycle-Tires, of which the following is a specification.

My invention consists of a semicircular shoe or covering of flexiblematerial lined with metal plates overlappin g and continuing from end toend of said cover, both of which are alike in curvature, form, and beingriveted or secured together for the purpose hereinafter set forth.

The figure represents an isometrical View of my invention, showing theseveral parts and arrangement thereof.

A simple form of constructing my invention is as follows: I take a pieceof rubber-lined cotton fire-hose G, in length somewhat longer than thecircumference of a wheel-tire A. This I split into halves or into twopieces. I

next select some sheet. spring-steel, (gage about thirty or iinerg)which I cut into pieces one-fourth the length of circumference ofwheel-tire A. These I bend or compress by suitable dies intosemicircular form and rivet them upon the inside of G, leaving the inneredges c, free and overlapping each other, as seen in t-he figure. Alongone edge of G, I secure straps Upon opposite edge I attach' buckles c,although said strap and buckle, or either, may be buttoned upon therivets e.

This completes construction, which may be applied as follows:

Measure the circumference of wheel and cut the cover to correspond.Proceed and place it onto the tire A, passing straps d around andunderneath the rimD. Let the straps engage the opposite button e. Bucklec and draw tight, as required. It will now be evident that the outermaterial will rej ceive andstand the wear, while the plates B willresist sharp substances, both serving to protect the tire A. This covermay be removed and replaced in a few moments and may be applied tovarious-sized wheels.-

Being aware of the use of protective metal tubes and like contrivances,I hereby specify that which 'I claim as new and desire to 'secure byLetters Patenti l An endless semicircular flexible outer shoe or casehaving upon the under side thereof` and made a part thereof a series oftransversely arc-shaped rectangular quadrant re'- silient metal platessecured to the edges of casing, their free ends overlapping the treadportion of a wheel-tire to which it may be secured by means of strapspassing under the wheel-rim substantially in a manner and for thepurposes herein set forth.
